[Paraview] RE: Seeding streamlines and 2 questions : Data Topologies and Sharp autostereo rendering

[Richard Strelitz]

Answer 1:  (for Stephen Wornom in France, a respectable distance from  
Vicksburg, MS)
Streamlines are seeded by using a vtk-geometry; even a set of points  
as an unstructured points object will work.  VTK does not have a  
topology extractor which would help you to find the vrotex cores and  
the strakes.

Question 1:
   Is there interest in a topology filter?  Any features that you'd  
like to have?  I need to write one, and it would be nice to have a  
collaborator or even an interested party.

Question 2:
   I have several Sharp 15" LCD autostereo panels plus the SDK for  
win and XP.  Has anyone toyed with a rendering module for these  
displays?  I quite like them, and although everyone wants stereo, no  
one wants to cede their desk to the CRT needed to display stereo.

Richard Strelitz,

The flow is external about a 3D cyl with strakes. I amI would like to
visualize streamlines behind the strakes and near the surface. The
streamlines created using a line or cloud are of little interest as they
miss the vortices behind the strakes. Is there a way to start the
streamlines from the cylinder and strake surfaces?
